In the endeavourshitherto made to reg11 late automatically by elect-ro-magnetic means :the run of the fabric or web edges indoubling various difliculties have been en;

machine's, countered, inasmuch, as the exposed electric to becomesoiled by the fabric dressing, and'theweight of the guide rods tojbe moved-isrelatively' large,

so that very substantial electro-magnet o forces are required for their movement, and the momentum which they-acquire is'inconvenient. Moreover the construction is complicated and its manufacture is expensive.-

The electro-magnets are switched on and off by a swinging feeler, which always follows up; the fabric edges automatically, also when the width of fabric changes by a small amount, by reason of .the various treatments to, which it is subjected, especially in dressing and drying ma- The annexed'drawings inflame. angel and 2 part of the improved doubling ma chines, in side elevation and inplan view respectively. 2 I The, guide ro lers with their electro-magnets are indicated in these figures by A;

Each of. the two carriers 39, .40 swings on its arm 36 about a pivot 43 and serves by its part 39a or 40a as an armature for the magnet 44 or 45 fixed to the angle arm 36;- Each angle arm can rotate on av'pin 46, 47 about a joint 48 and g is, bymeans of the said pin, adjustable as to height in a body 49 or 50 fixed on the rod 35, and also rotatable. Each body 49 and50,

. .37terminates below in a ball 53, which, to-

V pressed back slightly by the forward run however, is in turn slidable and in'clinable on the rod 35 so that the guide rollers 37, 41 and 38, 42 can be accurately set and adjusted in any desired position.

Instead of the device just described that illustrated in F igsf12 to 14 maybe employed, in which the arm 36 carrying the upper roller gether with a cup ,54 forms a universal joint. By means of a screw 56press'ing together the lugs of the cup 54 the fixing of the joint in'the desired position is possible. The pin 57 which carries the cup 54 is fixed on the rod 35 in such a way that it can be adjusted up and down in any required way.

If the fabric edges run correctly then both the contacts 30, 32 and 31, 33 are lifted off because, according to Fig. 4 the entire feeler device is constantly pressed gently against the edges of the fabric by the the width of fabric changesthen the feeler device gives way and the contacts continue to be lifted off both magnets 44 and 45 are deenergized in this case, so that the correctly running fabric edges pass 'uninfluenced between the two pairs of rollers 37, '41 and38, 42. As soon as one fabric edge, for example 5, runs'forward, the entire feeler device is ning edge. The other fabric edge 0 of course goes back relatively to Z), whereby the feeler lever 28 is brought under the actionof the spring 29 because the resistance of the goods 0 hasstopped (see Fig. 11), and thus the con-' tacts 31, 33 are closed. By this means the magnets 45 are energized whereby the rollers 38, 42 are pressed against each-other and the goods are drawn over to the'right until the edge 0 ofthe goods is drawn so far forward that it pushes the lever 28 forward and thus breaks the contact at 31, 33. In this way the magnetic action of the magnets 45 ceases,

the two rollers'38, 42 move apart, and the goods again run free. This operation is repeated according to which edge of the goods remains behind. I
